I am in the middle of my reno and I need to sketch out a stair drawing.
As you guess from title, these are steel.
Are there any web sites to help with a drawing?
I was mounting a three inch slab of wood mounted to a welded.L bracket.
The treads are 9.5 " deep, 36 inch wide by 3" . What size hole to be predrilled in the L bracket
and what size screw or bolt to attach from under side. And how many per side?
Located in Ontario if anyone has building code input.
